Auditory Pattern Perception I. Grouping Sounds a. Group by Proximity – grouping sounds that happen at the same location b. Group by Similarity (Timbre) – grouping sounds by their similar acoustic qualities II. Music a. Tone is controlled by frequency i. Tone Chroma – if a frequency is doubled, it produces the same tone in a higher octave ii. Tones are consonant when their frequency form a simple relationship 1. Ex – C-G = 2/1; C-E = 5/4; C-F = 4/5; C-A = 5/3 iii. Tones are dissonant when their frequencies form a complex relationship 1. Ex – C-C# = 262/277; C-D = 262/294; C-D# = 262/311 b. Gestalt principles also apply to sounds i. Participants group notes together from different ears in order to make note transitions seem more continuous than they really are ii. III.
